SH 4W DAVID A. BARLOW, OF ORANGE, CONNECTICUT.

ELECTRIC GAS-LIGHTING- MACHINE.

Specification of Letters Patent.

Patented April 21., 1908.

Application filed February 21, 1907. Serial N 0. 858,660.

To all whom it may concern:

Be it known that I, DAVID A. BARLOW, a citizen of the United States, anda resident of the town of Orange, in the county of New Haven, State ofConnecticut, have invented a new and useful Improvement in ElectricGas-Lighting Machines, of which the follow- 'ing is a specification,taken in connection with the drawings, which form a part thereof, and inwhich similar letters of reference represent like parts.

In the drawings Figure 1 is a plan view of my invention. Fig. 2, asectional View of the same, on. the lines X X, of Fig. 1.

The object of my invention is the construction of a device for lightingthe gas issuing from the burners of gas stoves by an electrical spark ashereinafter more fully described.

In the drawings A represents a gas range or stove, having a series ofgas plates A. Contact points a, are affixed to the gas plates A, andconnected with the positive post of a battery, in well known manner. I

Secured to the inner frame of the stove A, is a frame B, provided withextension arms B and B as shown in Fig. I. Said frame 'B, is insulatedat the points I) and l), and

provided with perforations b and b Horizontally extending rods Z), If, band b, are adapted to lit in said frame B, and to slide therein and bepulled forward by the operator against the tension of springs 5 l), I)and o for purposes more fully described hereafter, and whenreleased bythe operator the tension of the spring causes them to be returned totheir normal position in well known manner. On the upper surface of saidrods b b Z) and b, are secured laterally extending arms 0, c, c and 0having contact points (Z, d, d and d said contact points being adaptedto come in contact in their forward movement with the contact points a,on the gas plates A, as shown in Fig. 1.

Upright lugs c and e, are secured to the upper surface of said rods band b and as said rods are pulled forward bear against the outer side ofthe rear edge of frame B, and act as stops in the outward movement ofsaid rods, while laterally extending arms 0 and. 0'', when said rods 1)and b are pulled forward bear against the outer edge of said frame B,and act as stops for said rods, while a series of upright lugs e 6 e and0 are secured to the upper surface of said rods l), 5", b and 6 so thatwhen said rods are released.

against the tension of springs b b b and b, said lugs Wlll bear againstthe outer edge of said frame B, and prevent said rods from slidingbackwards through said perforations b farther than is desired wl'ienreleased by the operator, asshown in Fig. 1. Said horizontal rods in, b,b and W, are connected in well known manner, with a spark coil and inturn with the negative pole of the battery or batteries.

In operation the gas cook on a range con necting with the gas burnerwhich it is desired to light is turned on, in well knowlr manner, andthe rod having the laterally eX- tending arm over said burner is drawnforward by the operator until the contact point thereof comes in contactwith the contact point on said gas plate, thus sparking the same an digniting the gas.

Having now described my invention, What I clalm and desire to secure byLetters Patent, is

1. In a device of the class described, a stove provided. with a seriesof openings in the top thereof, contact points adjacent to the openings,a su porting frame, a base plate provided witr upwardly extending ears,said ears secured to the frame and said base late adapted to be securedto the stove top, raving openings in the ends thereof, independentlyreoiprocating rods having their bearings in said. openings, arms securedto certain of said rods outside of the supporting frame, said armsacting as stops to limit the vmovement of the rods to which they areattached, contact points carried by the'arms, and arms secured to theremaining reciprocating rods at a distance from their ends, said armsalso carrying contact points, the operative ends of the reciprocatingrods adjoining each other, alternating rods operating contact points onopposite sides of the frame.

2. In a device of the class described, a stove provided with a series ofopenings in the top thereof, contact points adjacent to the openings, asupporting frame, having openings in the ends thereof, independentlyreciprocating rods having their bearing in said openings, arms securedto certain of said rods outside of the su porting frame, said armsacting as stops to iimit the move ment of the rods to which they areattached, contact points carried by the arms, arms s'e cured to theremaining reciprocating rods at a distance from their ends, said armsalso carrying contact points, the operative ends hand at New Haven, inthe count of New of the reciprocating rods adjoining each Haven andState of Connecticut, this 8th day other, alternating rods operatingcontact of February, 1907.

points on opposite sides of the frame and DAVID A. HARLOW. 5 springs forautomatically returning the rods Witnesses:
